Thiszinvention relates to diamond point setters for driving glaziers points.

The main objects of this invention are to providean improved form of setting tool or driver which will set the glaziers point tightly and snuglyagainst the glass; to provide a driver which can be used for setting glaziers points on exceptionally small panes of'glass; and to provide a generally 'improved and'efficient deviceQof this-charac ter. r

An illustrative embodiment of. this inven-:

Heretofore in theconstruction ofglaziers point" setters, the devices have been constructed so "that the front drivingend pithe'. ram which drives the glazierls pointeither rests upon'th'e glass when in position torgu'se. l

In the case wherethe frontend of the driver is supported by a transverse cross strip; the glaziers pointis always set in the cross bar of the window 'framein'slightly spaced relation tothe glass and'there also the glass is onlyc'loosely fastened in the v .7

After many years experience in using Va; rious types of prior art setters of this character, Ihave found that in order to secure 7 a pane Ofi 'lass snugly and-tightly inra'i'rame Vwhenzusing a glazierspoint driver 'itvis es-v Y sentialthat the position of thedevice be det'erininedsolelyby the surface ofthe pane 'of -gglassz'w'hich is, being-fastened in i the frame. zIn my present'eonstruction, the sup-Q porting legsof the=dr1ver have been so varranged that the entire weight of the device and its position when in useis determined solely by the pane of glass being glazed and :in this manner Isecure a very high-grade. tight-fitting ob. ofglazing.

In; the construction shown inthe draw- "ingsi the driver comprises a hollow handle 1 V V which is preferably" constructed from two parts longitudinallyfsplit and secured to-v,

getherJ, A magazine 2 is integrally formed- "at the front end of the handle 1 for carrying a f quantity er; diamond shaped glaziers points 8,7which are norinally yieldably urged and-pushed downwardly in the magazine by :1.

The upper, end fof the plunger 1s surroundedby a helical tension spring 6 which has one" end thereof secured to yoke 5; andthe other end secured to head? ,mo'unted 1011 the upperend of the plunger h aThe spring 6,"1plunger 4 and and 10. The guides 9 and 10 are integrallyformed at the lower end of the magazine and extend horizontally longitudinally of the driver. The rear end of the driving rainis mounted upon a driving block 11 which has a horizontally rearwardly extending plunger rod 12 rigidly pinned thereto at its front end. The rear end of the rod 12 is slidable [through a depending'bracket 13 integrally formed on the handle 1 and ahelical compression driving spring 1 1 surrounds the rod 12 and bears between the block 11 and the inner side of the bracket 13.

Means are provided for retracting the block 11 rearwardly against the action of the spring 14 a sufficient distance to uncover the bottom'of the magazine 2, and comprises a trigger 15 pivotally mounted by a pin 16 at the front end of the handle 1 immediately behind the magazine 2. The trigger 15 is in the form of a bell crank, the other arm 17 of which depends from the point of pivotal mounting, and a vertically disposed steel strip 18 is riveted or otherwise suitably secured to the lower end thereof. The lower tip end of the strip 18 abuts against the front end of a horizontally disposed pawl 19 pivotally mounted by a pin 20 in a medially disposed longitudinally extending channel formed in the upper side of the block 11.

A helical compression spring 21 is provided underneath the pawl 19 at the front end thereof and bears between the underside of the pawl and the floor of the channelwa-y within which the pawl is mounted. A set screw 22 is threaded through the rear end of the pawl 19 for adjustably positioning the front end of the pawl with respect to the lower end of the plate 18, the pawl having rocking movement on its pivot.

The trigger 15 is provided with an up wardly and rearwardly extending. arm 23 which bears against a flat spring 24 mounted within the handle lfor normally urging the trigger 15 to the position shown in Fig. 1.

At each side of the front end of the device there is provided supporting legs 25' and 26 which are rigidly secured by screws '27to the sides of the vertically extending portion of the framework within which is contained the magazine 2. These supporting legs are of L shape with the vertical portion secured to the frame of the device and the horizontal portion thereof extending 'rearwardly and bowed outwardly as shown at 28. These supporting legs are positioned and arranged on the device so as to support the driving ram ger 15. The tri er 15 is 8 in very slight spaced relationship to the surface of the pane of glass upon which the driver rests, as shown most clearly in Fig. 3.

In the operation of this device, the head 7 of the plunger 1 is grasped and drawn outwardly until the'lower end of the plunger is withdrawn from the magazine 2, at which time the plunger and its supporting yoke 5 are rotated'forwardly so as to clear the upper end of the magazine. A package of diamond shaped glazier.s points is then placed in the magazine and the yoke and plunger swung back to a vertical position, at which time the plunger is released thus permitting the spring 6 to yieldingly urge the lower end of the plunger 4 down onto the top of the glaziers points within the magazine.

lVhen it is desired to glaze a pane of glass, the driver isplaced upon the pane with the front end thereof abutting the cross bar of the window. It is to be noticed that the arrangement is such that the entire device is supported upon the pane of glass being glazed, even though the pane be of small size,

the plunger 12 and its driving spring 1 1 being inspa'ced relation above the glass so as to clear any intervening cross bar, as shown particularly in Fig. 1.

The handle 1 is grasped by the user with the fingers thereof passing around the triggg drawn upwardly by the fingers thus causing the bell crank arm 17' and plate 18 to push the driving block 11 rearwardly against the action of compression spring 14:. The block 11 is supported by the rear end of the rod 12 passing through the bracket 13 and the'front end of the driving ram 8 being slidably mounted on the guides 9 and 10.

When the trigger 15 has been raised to a certain point the lower end of the strip or plate .18 slips off of the forward-end of the pawl 19, thus permitting the compression driving spring 14 to drive the block 11 forwardly. During the time of retraction of the block'll, a glaziers point has been fed downwardly by the plunger 4 out of the lower end of the magazine 2 in position to be en gaged by the front end of the ram 8. This front end of the ram 8 is provided with a V-notch' of the same conformation as onehalf of the diamond shape glaziers point. Forward movement of the block 11 and ram 8 causes the ram to engage the glaziers point which has been fed down and drive it into the cross bar of the window frame. As the clearance of the ram 8 is very slight with respect to the pane being glazed, the driven point is put in position snugly against the surface of the glass.

The trigger 15 is then released and the spring 24 tends to rotate it in a right hand direction, as viewed in. Fig. 1 of the drawings, thus causing the plate 18 to contact with the upper surface of the pawl 19 and depress the same against the action of the compression spring 21. When the trigger has assumed its original position, the plate '18 will have passed'the outer end of the pawl 19 and said pawl will again resume its normal horizontal position by the action of the com pression spring 21.1 Adjustment of the front end of the pawl with respect to the strip 18 may be secured byrotation of the set screw 22 in the appropriatedirection. This adx j ustment will vary the stroke of the ram within reasonable limits. o 1
